21. Dark Matter in the Galactic Halo : A Search Using Neutrino Induced Cascades in the DeepCore Extension of IceCube
Sammanfattning : A search for Weakly Interacting Massive Particles (WIMPs) annihilating in the dark matter halo of the Milky Way was performed, using data from the IceCube Neutrino Observatory and its low-energy extension DeepCore. The data were collected during one year between 2011 to 2012 corresponding to 329.1 days of detector livetime. LÄS MER
22. Phenomenology of neutrino properties, unification, and Higgs couplings beyond the Standard Model
Sammanfattning : The vast majority of experiments in particle physics can be described by the Standard Model of particle physics (SM). However, there are indications for physics beyond it. The only experimentally demonstrated problem of the model is the difficulty to describe neutrino masses and leptonic mixing. LÄS MER
23. On the Search for High-Energy Neutrinos : Analysis of data from AMANDA-II
Sammanfattning : A search for a diffuse flux of cosmic neutrinos with energies in excess of 1014 eV was performed using two years of AMANDA-II data, collected in 2003 and 2004. A 20% evenly distributed sub-sample of experimental data was used to verify the detector description and the analysis cuts. LÄS MER
24. Search for Neutrinos from Gamma-ray Bursts using the IceCube Neutrino Observatory
Sammanfattning : Gamma ray bursts (GRBs) are short bursts of high energy γ-radiation and are among some of the most energetic phenomena in the universe. GRBs have three distinct emission phases: the prompt phase with high-energy γ-rays, the precursor phase which is the time interval before the prompt phase and is reported to have an additional smaller burst for some GRBs, and the afterglow phase which is the time interval after the prompt phase with observations for electromagnetic radiation across a large wavelength range reported for many GRBs.
